FSO2N3-Enabled Synthesis of Tetrazoles from Amidines and Guanidines.
Organic Letters, 2023Herein we report the facile syntheses of tetrazoles enabled by FSO2N3 under mild conditions. FSO2N3 has been shown as the most powerful diazotizing reagent, which converts thousands of primary amines to azides fast and orthogonally.

Metal-Free Regioselective N2-Arylation of 1H-Tetrazoles with Diaryliodonium Salts.
Journal of Organic Chemistry, 2022We describe a simple, metal-free regioselective N2-arylation strategy for 5-substituted-1H-tetrazoles with diaryliodonium salts to access 2-aryl-5-substituted-tetrazoles.

Nitroimino-tetrazolates and Oxy-nitroimino-tetrazolates
Journal of the American Chemical Society, 2010Highly energetic 1,1'-ethylenebis(oxy)bis(5-nitroimino-tetrazolate) salts were obtained by reacting equimolar quantities of the acidic 1,1'-ethylenebis(oxy)bis(5-nitroimino-tetrazole) and energetic bases in aqueous solution. Additionally, metathesis of silver 1,1'-ethylenebis(oxy)bis(5-nitroimino-tetrazolate) with diaminoguanidinium chloride or ...
